API 650 SUG III tanks data sheets

Protection of Plates during Shipping and Storage
Plates shall be adequately protected during shipping and storage to avoid damage to API 650 SUG III tanks material plate surfaces and edges from handling (scratches, gouge marks, etc.) and from environmental conditions (corrosion, pitting, etc.).
Plates shall be protected from moisture or stored in inclined position to prevent water from collecting and standing on surface.

The advantages of API 650 floating roof tanks have obvious environmental and economic benefits: in a specific climate environment, according to historical data, the economic value of the API 650 SUG III tanks floating roof tanks in API 650 due to the reduction of oil and gas volatilization within 3-6 months is equivalent The installation and purchase cost of the API 650 SUG III tanks inner floating roof means that the cost of the inner floating roof can be recovered within half a year.

Ultrasonic testing can find the internal defects of API 650 SUG III tanks welding joint, this detection method is very accurate for the internal layer defects of oil tank, but ultrasonic detection is not suitable for the detection of thin-walled storage tank materials. Dye penetrant testing is only suitable for detecting the defects of the surface opening of API 650 SUG III tanks and so on metal oil tanks. The feature of this method is convenient and fast.
